I would suggest to look a bit deeper at why it is needed first - and
then try to change the root cause.
I've been using the jpgeint.h CSTATE_* defines for optimized decoder
loops (i.e. stoping decoding as soon as the size is known). This is a very
specialized application, and I realy needed this (since libjpeg decoding
is awfully slow). I can't realy thing of other common uses of jpegint.h,
and this could be abstracted into a few state-checking macros.
I think that
- either graphics/jpeg should install the jpegint.h header - since some
applications need it (as the comment in that file suggests)
- or we should convince the libjpeg people to add the missing state-checking
macros to jpeg.h (like #define JPEG_DECODE_PROPS_KNOWN(state)
((state)>=202), and probably a few others)
